Abstract

A system and method for analyzing and providing exception-based reports for machine data. The machine data is relayed to a remote system for automated analysis based on tests and parameters defined by an owner. If any exceptions are detected in the data based on the operator-defined input, output is generated. The output may take the form of exception-based printed or electronic reports, or the exception information may be relayed to a hand held device, preferably maintained by service personnel at the work site.

Claims

1. A method of diagnosing a machine, comprising:

transmitting operating parameter data from a plurality of machines to a remotely located control system configured to receive the transmitted data;

storing the received operating parameter data from the plurality of machines on the control system;

selecting at least one test to be performed on the stored data by selecting from a plurality of available tests;

defining a plurality of machine sets by grouping machines of the plurality of machines into different groups based on commonalities amongst the machines in a group; and

selectively executing the at least one test on a machine set of the plurality of machine sets.

2. The method of claim 1, wherein selecting the at least one test includes defining at least one testing procedure, wherein defining the at least one testing procedure includes defining a script comprised of one or more tests of the at least one test to be conducted automatically on the stored data.

3. The method of claim 2, wherein defining the at least one testing procedure includes defining at least one test that is to be automatically conducted based on a result of another test.

4. The method of claim 1, further including collecting the operating parameter data using one or more sensors coupled to each machine of the plurality of machines.

5. The method of claim 4, wherein the plurality of machines includes one or more machines operating at a first work site and one or more machines operating at a second work site remote from the first work site.

6. The method of claim 1, wherein defining at least one test includes defining one or more parameters associated with the at least one test, wherein the one or more parameters include values of operating parameter data that indicate a normal operation of a machine of the plurality of machines.

7. The method of claim 1, further including reporting a result of the executed test, the result being reported only if the executed test indicates a fault.

8. A method of diagnosing a machine, comprising:

collecting operating parameter data from a plurality of machines operating at a first work site;

transmitting the data to a computer system located at a location remote from the first work site;

storing the transmitted data in a storage device of the computer system;

defining a plurality of machine sets by grouping machines of the plurality of machines into different groups based on commonalities amongst the machines in a group;

associating the stored data with a machine set of the plurality of machine sets based on a source of the data;

selecting at least one test to be performed on the associated data;

selectively performing the at least one test on a machine set of the plurality of machine sets; and

selectively reporting a result based on an outcome of a test of the at least one test.

9. The method of claim 8, wherein selective reporting the result includes transmitting the result to a display located at the first work site.

10. The method of claim 8, wherein selectively reporting the result includes reporting the result only if the outcome of the test indicates a defect in a machine.

11. The method of claim 8, wherein selecting at least one test includes selecting one or more tests from a list of available tests stored in the computer system.

12. The method of claim 8, wherein selecting one or more tests includes selecting at least one parameter associated with at least one test of the one or more tests.

13. The method of claim 8, further including selecting whether or not the selected at least one test should be conducted in a real time manner.

14. The method of claim 8, wherein performing the selected at least one test includes performing the at least one test on the stored data at a first time and automatically repeating the at least one test on the stored data at a second time later than the first time.

15. The method of claim 8, wherein selecting at least one test includes choosing a time for performance of the at least one test, and performing the at least one test includes performing the at least one test at the chosen time.

16. A computer based system for diagnosis of a machine, comprising:

a storage device storing operating parameter data of a plurality of machines, the storage device being located remote from the plurality of machines; and

a processor configured to;

define a plurality of machine sets by grouping machines of the plurality of machines into different groups based on commonalities amongst the machines in a group;

associate the stored data with a machine set of the plurality of machine sets based on a source of the data;

enable the selection of at least one test to be performed on the associated data from a plurality of available tests;

selectively perform the at least one test on a machine set of the plurality of machine sets; and

report a result of the at least one test if the result indicates a defect in a machine.

17. The computer based system of claim 16, wherein the plurality of machines include machines that are located at different work sites.

18. The computer based system of claim 16, wherein each of the plurality of machines include sensors configured to acquire operating parameter data.

19. The computer based system of claim 16, further including one or more transmitters configured to wirelessly transmit data from the plurality of machines to the storage device.
